This is the first & only time I'll make a comment about this but these are my thoughts. I don't believe the issue here is that people actually feel threatened by trans people using the restroom they are comfortable with considering they've been doing it for ages without you being bothered by it because you don't see other people's genitals in public restrooms. Also, when it comes to people saying that they are worried about their children- if that's actually your true concern, why don't you fight to make it illegal for registered sex offenders to use public restrooms?? Not that there would be a way to enforce that- but if that was honestly your worry, why wouldn't you start there?? I think this is more about your lack of understanding and willingness to understand trans people because the thought is different/uncomfortable for you.
